Overview of New Information Transmission Methods in Power Systems
Compared to power systems that use traditional RS485/CAN buses as transmission methods,the new power system has put forward new requirements for the radiation,efficiency,and power of information transmission methods. Therefore,the article first introduces common information transmission methods,then elaborates on the principle of information power composite modulation from the essence of power electronics,analyzes the advantages and disadvantages of common digital modulation methods,and finally summarizes the current urgent problems and development prospects. The application of information composite modulation technology is quite extensive. When combined with the current flexible,efficient,and environmentally friendly distributed energy,it can not only improve energy utilization efficiency,reduce energy consumption and emissions,but also promote the development of new power systems and renewable energy,making important contributions to achieving sustainable global energy development.
